Christoph Baumhauer, a preacher of the Hutterian Brethren in Sobotište, Hungary, who, together with Jakob Amssler on 8-18 October 1655, received the consent of Elector Karl Ludwig of the Palatinate to establish a settlement of the Hutterian Brethren in Mannheim; several families settled here; Baumhauer returned to Hungary. After the great destruction brought about in Hungary by war, he was commissioned to seek help from the churches in Holland. With Benjamin Polay, also a preacher, he left for Amsterdam on 21 April 1665, by way of Mannheim, visiting also the churches in Zeeland, Flanders, and Friesland. On 27 October they arrived at home with the Dutch gifts (a letter of thanks, dated 24 November 1665 to the Dutch churches, is in the [[Amsterdam Mennonite Library (Bibliotheek en Archief van de Vereenigde
Doopsgezinde Gemeente te Amsterdam)|archives of the Amsterdam church]], No. 2851). Baumhauer died on 31 October 1681 at Dechtiz, at the age of 60, having served as a preacher for 31 years.
